A household radio favorite for millions of depression era housewives was the drama
series “The Guiding Light”. NBC radio presented the first broadcast of the longest-
running story line in daytime drama. The show moved to CBS Radio in 1947 and
began a long run on CBS-TV in 1952 that ended in 2009 due to poor ratings. The
original radio program of 15 minute episodes was sponsored by Procter & Gamble.
